[OBD Connect Edition Update 6 C#] DgnECManagedCrudExample

Hi,

I am currently trying to adapt the 'DgnECManagedCrudExample' (https://communities.bentley.com/products/programming/microstation_programming/b/weblog/posts/ec-crud-operations-with-native-and-managed-dgnec-apis#CreateECInstancesAndRelationships) to our needs.
It works fine with the simple (custom) schema from the example.

If I try with the class 'Concrete__x0020__Column' from the 'BuildingDataGroup' schema I run into an 'EnvironmentalException' ("CreateInstanceOnElement failed with error code: 32768") when I try to create the 'IDgnECInstance'. The 'SupportsCreateInstanceOnElement' flag is also false (it´s true in case of the simple schema). I tried the other methods of creating an instance in 'DgnECInstanceEnabler' as well.

bool supportsCreateInstanceOnElement = widgetEnabler.SupportsCreateInstanceOnElement;
IDgnECInstance widgetInstance = widgetEnabler.CreateInstanceOnElement(lineElement, widgetWipInstance, false);

I have columns with that exact EC instance attached in the same model.

Am I missing something here? Is this not allowed?

Cheers

My example code:

DgnFile activeDgnFile = Session.Instance.GetActiveDgnFile();

ModelId modelId = activeDgnFile.DefaultModelId;
StatusInt statusInt;
DgnModel activeDgnModel = activeDgnFile.LoadRootModelById(out statusInt, modelId, true, true, true);

DgnECManager dgnECManager = DgnECManager.Manager;

DPoint2d startPoint = new DPoint2d(0, 0);
DPoint2d endPoint = new DPoint2d(10 * UoR, 10 * UoR);
DSegment3d segment3D = new DSegment3d(startPoint, endPoint);
LineElement lineElement = new LineElement(activeDgnModel, null, segment3D);
if (null != lineElement)
lineElement.AddToModel();

string schemaName = "BuildingDataGroup";
FindInstancesScope scope = FindInstancesScope.CreateScope(Session.Instance.GetActiveDgnFile(), new FindInstancesScopeOption(DgnECHostType.All, false));
IECSchema schema = DgnECManager.Manager.LocateSchemaInScope(scope, schemaName, 1, 0, SchemaMatchType.Latest);

string className = "Concrete__x0020__Column";
IECClass ecClass = schema.GetClass(className);

DgnECInstanceEnabler widgetEnabler = dgnECManager.ObtainInstanceEnabler(activeDgnFile, ecClass);
ECDInstance widgetWipInstance = widgetEnabler.SharedWipInstance;

bool supportsCreateInstanceOnElement = widgetEnabler.SupportsCreateInstanceOnElement;
IDgnECInstance widgetInstance = widgetEnabler.CreateInstanceOnElement(lineElement, widgetWipInstance, false);
